Subclass in PvE in DFO
In DFO, we suspect the answer is summoned, but witches can cause some mayhem with lava potion, rain, and the tier 3s. Element lists skills are not as flashy as the witch spells, we find, but they also have a shorter cool down and tend to do more damage. We have no experience with gunners, so we can not comment on mechanic, launchers, or spitfires. Grapplers, once they get to a high level (Dungeon Fighter Online gold), can cause chaos as their big throws are visually impressive and they also move enemies around a lot, which really annoys parties.
We feel like sitting back and creating chaos, but we are finding our level (Dungeon Fighter gold) 31 witch's spells to lack power, but they sure do look pretty. Our summoned turns any dungeon into a mosh pit, but we are looking for something a little less passive. We would go for a launcher, but we suspect mana is a major issue. Our experience with asuras has told us that we really hate chugging mana potions every dungeon. Same thing with mechanics, though we really have no experience whatsoever with gunners as a whole.
